Answer:

19 units

Explanation:

You have midline LM marked as 6x+1 and parallel baseline IJ marked as -6x+56 in triangle IJK. You want to know the length of LM.

Midline

The midline of a triangle is half the length of the parallel base:

LM = 1/2(IJ)

6x +1 = 1/2(-6x +56) . . . . . substitute expressions

6x +1 = -3x +28 . . . . . . . simplify

9x = 27 . . . . . . . . . . . . sdd 3x-1

x = 3

Now, we can find LM:

6x +1 = 6(3) +1 = 19

The measure of LM is 19 units.
